Hi,<div><br></div><div>It seems that it is complaining about not having sched-cred, that it is used to implement the capacity distribution set in OpenNebula (a VM with CPU=0.5, will be assigned a proportional amount of credits so it gets half of the credits of a VM with CPU=1.0)</div>
<div><br></div><div>Just edit $ONE_LOCATION/var/lib/remotes/vmm/xen/deploy.sh and comment the line that refers to sched-cred. Use onehost sync (and wait for a monitoring action on the hosts....)</div><div><br></div><div>

</div></div>You may want to use libvirt 0.9.0 if it is supported by OpenNebula.<br>
<br>
The key feature added is:<br>
<br>
* Add libxenlight driver (Jim Fehlig and Markus Groß)<br>
<br>
<a href="http://article.gmane.org/gmane.comp.emulators.libvirt.user/1229/match=libxenlight" target="_blank">http://article.gmane.org/gmane.comp.emulators.libvirt.user/1229/match=libxenlight</a><br>
<br>
I'm not familiar enough with the errors that OpenNebula is showing<br>
above, but libvirt support for libxenlight/libxl is the way forward<br>
(xend is deprecated as of 4.1)<br>
<br>
Some further Xen information that may be helpful<br>

Let Xen.org know if we can be helpful in troubleshooting the<br>
Xen/libvirt side of things.<br>
<br>
Thanks,<br>
